Our picks: Tissot PRX 40mm Quartz (T137.410) (the quartz case), Tissot PRX Powermatic 80 (Ice Blue) (the automatic case). Full reasoning, verified specs, and a comparison table below.
How We Compared
We compared the two current 40mm PRX lines on movement, case feel, dial execution, and long-term ownership economics — drawing on the deepest-reviewed listing of each. Both are the real PRX; they simply answer different questions. New to the model? Our automatics under $1,000 guide places the Powermatic in its wider field, and a winder keeps it running between wears.
The Quartz Case: Tissot PRX 40mm Quartz (T137.410)
Tissot PRX 40mm Quartz (T137.410)
Tissot
- Slim quartz case — noticeably thinner under a cuff
- Same 316L integrated case and bracelet as the automatic
- Swiss quartz accuracy, battery every few years
- Sunray dial finish
- 4.6★ from 370+ owners — 100+ bought in the past month
Why we picked it: The quartz PRX is the design at its purest: every line of the 1978-revival case, slimmer on the wrist than the automatic, at a price that makes it the single best value in the entire integrated-bracelet trend. Owners rate it above the automatic. If the look is what you're buying, this is the one.
The Automatic Case: Tissot PRX Powermatic 80 (Ice Blue)
Tissot PRX Powermatic 80 (Ice Blue)
Tissot
- Powermatic 80 automatic — 80-hour power reserve
- Waffle-texture dial exclusive to the automatic
- Exhibition caseback showing the movement
- Ice blue — the collector-favorite colorway
- 4.8★ from 98 owners
Why we picked it: The Powermatic is the PRX collectors keep: a mechanical heart visible through the caseback, a textured waffle dial the quartz doesn't get, and a movement that runs three days off the wrist. The ice blue is the colorway of the moment. It costs more and sits taller — and it's the one you'll still be winding in twenty years.

How to Decide
Buy quartz for the design, automatic for the object. If the PRX pull is how it looks on the wrist, quartz delivers 100% of that for the least money and the slimmest profile. If the pull is owning a mechanical Swiss watch, only the Powermatic scratches it. Neither buyer regrets their logic — only borrowing the other's.
The 80-hour reserve is the automatic's killer spec. Most automatics die overnight-plus-a-day; the Powermatic 80 runs from Friday removal to Monday morning with hours to spare. It converts the classic automatic annoyance into a non-issue.
Thickness is the quartz's quiet win. The quartz PRX slides under shirt cuffs the way 1970s originals did. The automatic's extra height is modest but real — try both on paper measurements if you wear tailored shirts daily.
Ownership economics differ long-term. Quartz asks for a battery every few years; the automatic wants a proper service every 5–7. Over a decade the automatic costs more to run — the price of a living movement, and worth stating plainly.
Bottom Line: Which Should You Buy?
For the design at its purest: the PRX Quartz — the icon's look, slimmest and most affordable.
For the mechanical keeper: the PRX Powermatic 80 — waffle dial, glass back, 80 hours of heartbeat.

Frequently Asked Questions
Is the Tissot PRX Powermatic 80 worth the extra over quartz?
If you value mechanical watchmaking, yes — the movement, waffle dial, and exhibition back are genuine upgrades, not padding. If you're buying the design, the quartz gives you all of it for much less. Both are 'real' PRXs.
How accurate is the Powermatic 80?
Expect within tens of seconds a week and a full 80-hour reserve — strong for an automatic at any price. The quartz stays within seconds a month; accuracy is simply what quartz does better, full stop.
What sizes does the PRX come in?
The core lines run 35mm and 40mm, with the automatic also offered in special dials and materials. The 40mm reviewed here is the definitive proportion for most wrists; the 35mm suits slimmer wrists superbly.
Does the PRX quartz have the waffle dial?
No — the waffle texture belongs to the Powermatic 80 lines; quartz models carry a sunray finish. It's the fastest way to tell the two apart across the case.
Is the Tissot PRX a good investment?
It's a good watch — buy it to wear. That said, the PRX is this era's defining accessible integrated-bracelet design, and defining designs (Royal Oak, Nautilus at another altitude) have historically aged best. The ice blue Powermatic is the collector consensus.
